In an effort to address this problem, the nonprofit Global Citizen is partnering with Ekocycle, which makes clothing and other products with post-consumer waste, to bring you A Day Without Waste on April 9th. The campaign targets wasteful consumer habits, like getting disposable bags when you shop, ordering meals to-go and coffee served in single-use cups.

To show the world how simple and lovely life can be with less trash, they've made this charming video comparing the to-go lifestyle with a less disposable mentality:

To sweeten the deal, Global Citizen also has a rewards system if you make a profile at GlobalCitizen.org. By sharing how you reduce waste on Facebook and Twitter, you can earn points that get you concert tickets to shows around the country.

Global Citizen was started in 2010 to target millennials, and for the past two years they've organized the Global Citizens Festival with headliners like Stevie Wonder, Kings of Leon, Alicia Keys and John Mayer.

Ryan Gall, co-founder of Global Citizen, told me he believes many young people want to be part of the solution to the problems our generation faces. "The reality is that a lot of people need a little bit of a push and they need a bit of a direction to know what actions to take," he said.

"So we created GlobalCitizen.org and the Global Citizen Festival in order to reward supporters who take certain social actions." These actions include raising awareness on social media, but also extend to more concrete actions like volunteering and making small lifestyle changes, likes the ones that are part of the campaign for #ADayWithoutWaste.

"We wanted to come up with a fun way to remind people of how small steps can really have a big impact," said Gall. "Whether it's food waste or plastic waste, how you live and the choices you make affect everybody."
